Air quality in NYC typically recovers within a few days to weeks after wildfire smoke dissipates, depending on weather conditions.

Estimated Duration: 7 days

The recovery time for air quality after wildfire smoke affects a region like NYC depends on factors such as wind patterns, rainfall, and ongoing fire activity. Typically, once the smoke plume moves away and no new smoke is introduced, air quality can return to normal levels within a week. Persistent wildfires or stagnant weather conditions may prolong this process. Monitoring local air quality indexes (AQI) and following health advisories during this period is recommended. Indoor air purifiers and limiting outdoor activity can help mitigate health risks during recovery.
